6 Claims.

This invention relates to an improved telephone booth. It is the objectof this invention to pro- .vide a fire-proof and substantiallysound-proof tachable inner shell or lining, also preferably' formed ofmetal, spaced from the outer shell to provide room for sound insulatingmaterial between the shells, a removableV ceiling assembly and a specialdoor construction.

The novel features of design and structure by means of which theseobjects are accomplished may best be described in Vconnection with. theaccompanying drawings, which show a preferred embodiment of theinvention and various modiflcations.`

Fig. 9 is a detail sectional View showing the manner of attachment ofthe ceiling assembly to Fig. 10 is a detail view, in perspective, of amodied form of the structure shown in Fig.-9, and

Fig. 11 is a detail view in section showing a further modied form of thestructure shown in Fig. 9.

The outer wall I of the booth comprises a reotangular shell of sheetmetal, preferably one piece, extending from the floor to the roof of thebooth except for an opening in one wall forming a doorway. The outerwall may be embossed, as at 3, to give a decorative effect to the booth,

The upper edge of the outer wall I is folded back upon itself at 5 andthen folded atl rightl angles to'form. a flange 'I extending entirelyaround the wall I adjacent its 'upper edge. Se-

cured to the flange 'I by means of machinescrews 9 is ceiling II,likewise formed of sheet metally The ceiling vII is provided with alglass-covered aperture I3, through whichY light fromaglamp placed inthe space above the ceiling may illumine the interior of the booth,andralso with an opening I5 providing communication'withthe interior ofhollow standard I1.

y Secured tothe flange portion gIS of the ceiling I 'I I andextending'entirely around-the ceilingis a channel member 2|. The web rofthis channel member is -punched out'to forma plurality of kopenings 23communicating with thespace above the ceiling. Carried on the channelmember, but not secured thereto, is a roof 25,'medially hinged at 27 toafford easy access to the space 29 above the ceiling.

The plate-35 may thus be easily removed and replaced by a plate ofsimilar dimensions carrying any desired notice or advertisement, asTelephone, etc. Y

In the modied structure shown in Fig. r11, the

ceiling rI la is provided W1th an upstanding rib 22 formed by bendingthe material back on itself, and the roof 25 is supported -on this rib.A plurality of openings 23a are formed in the rib 22 to providecommunication with the space 29.

In the construction shown in Fig. 10 the outer wall I is not doubledback but is strengthened at its upper edge by an angle iron39 whichextends completely around the booth except in that portion above thedoorway. The ceiling I I is then securedV to the angle iron 39,'while amodified backing plate'3Ia is secured to the wall I above the doorway.`At one point, preferably inv the front of the booth, Where theone-piece outer wall I is joined together, flangeslare bentinwardly fromthe outer wall Iand welded at 4 to form a projecting rib whichcooperates with a corresponding slot 43 inthe flange I9 of the ceilingII to center the ceiling in position;

Extending around three sides of the booth'interior and secured to theinner face Vof the outer l 20 That portionrof the outerzwalll above thedoory wall I somewhat below the top thereof, but above the level of thelower part of the ceiling II is a Z bar 45. In each of the corners' ofthe booth interior are columns 41 of W-cross-section welded to the outerWall I and extending from the oor to the level of the bar 45. Secured tothe inside of outer wall I medially of each of the two side wallportions thereof are two columns 49 of door spreader bar vcross section,extending likewise from the floor to the level of the bar 45. An openingin the web of 2 bar 45 aiords communication between the interior ofcolumns 49 and the space above the lower level of ceiling II. A pair ofchannel members 5| positioned on each side of the doorway and extendingfrom the floor to the top of the doorway support the front Wall portionof outer wall I which is welded thereto.

Sheet metal panels 53, extending about the side and back walls of thebooth, form the inner booth wall. These panels extend from the level ofZ bar 45 to about six inches from the iioor and completely close thespace between the adjacent columns 41. Spring flanges 55 on the sideedges of each panel enable the panels to be snapped into place betweenthe columns 41 and held tightly in' position while remaining readilyremovable. The upper edges of the panels 53 are clamped between the bar45 and an angle iron 51 by means of machine screws 59.

In Fig. 5, slightly modified panels 53a are provided with inturnediianges 56 on their upper edges, and are thus held against possibledownward slipping.

The space between the panels 53 and the outer wall I is lled with soundinsulating material 54 preferably formed in compressible bats or slabsof slightly greater original thickness than the space between the walls.

The floor assembly 9| is formed by blanking out a piece of sheet metalinto the shape shown in Fig. 6, radial corrugations 63 being formed atthe same time. Sections 55 are then bent up at right angles to sectionB4, sections B1 are dished downwardly so as to bring the corners 68almost but not quite to the level of corrugations 53, and section 59 isbent back upon section G4 and tapped holes 'I0 made in the doubledportion.

The floor and wall assemblies are joined by welding the lower portion ofwall I to the upright portion 95 of the oor assembly. A sheet metalspacer 1I is then welded i'n place on the inside of the lower portion ofwall and a composition flooring I3 laid over the floor 54 and up againstthe spacer 1I for a height of about six inches to form a baseboard 14. Ametal protecting strip 15 extends across the floor at the doorwayopening and is secured by screws 11 set in the tapped holes`10. Theupper edge of the base board 14 is securedr tothe'spacer 1| by a U-shaped molding clip 19 which is snapped over and engages the baseboard14 and a flange 8| extending upwardly from the spacer 1I. This moldingclip 19 also serves to retain the lower edge cf panels 53 forming theinner wall in place. If desired, the molding clips 19 may be formed asan integral part of the panels 53.v

A seat S3 is mounted on a spindle 85 which in turn is secured in aA,base or socket member 81. Bolts 09 secure the base 81 through thebaseboard 14 to the spacer 1|.

The hollow cylindrical standard I1 is secured to the floor 64 by anysuitable means (not shown) and is secured at its upper end in theaperture I5 in ceiling Il, To standard I1 is secured a fixed sleeve 93carrying a bracket 9| and slidable on the standard I1 are two sleeves95, 91 carrying brackets 99, IDI. Securable to the brackets 9|, 99, |0Iin two positions so as to be secured at two heights from the floor isbackboard |03 and shelf |05 secured thereto, which serve to carry thetelephone instrumentalities. Apertures 101 in the standard I1 serve topermit the necessary wiring for the telephone instruments to be carriedinto the interior of the standard. The specific construction of thetelephone stand above described and its connection to the standard I1 isdescribed in more detail in my copending application Serial No. 122,363,led Jan. 25, 1937, and is specifically claimed therein.

The door |09 of the telephone booth will preferably be formed Vof sheetmetal, and desirably will be of the two-leaf type specifically describedand claimed in my copending application Serial No. 120,324, led Jan. 13,1937. The door, however, may be of any conventional type. It issupported by hinges III secured to one of the channel columns 5I. Thefree edge of the door is guided from open to closed position by means ofa roller or ball bearing assembly II3 secured in a bracket I|5 mountedon the upper edge of the door |09 and traveling in track I|1 of channelcross-section supported by brackets IIB secured to the spacer plate 3|and the outer wall I.

Wiring for the supply of electric current to lights, fan, etc. (not.shown) positioned in the space 29 above the ceiling II will be broughttol the top of the booth, carried aroundvthe booth to the point desiredinthe channel I|9 of channel member 2|, and passed through apertures 23to the space 29. These apertures 23 also serve as air inlets to space 29for ventilation purposes. The telephone wiring will be brought into thespace 29 in the same manner and then passed through aperture I5 downtheinterior of column I1 and so through holes I 01 to the telephoneinstruments on shelf |05. The vertical channel |2| in the side walls ofthe booth formed by channel member 49 and outer wall may also be usedfor wiring purposes. Access to this channel may be had through thebottom by piercing the floor 51 and the horizontal portion of spacer 1|,through the top by piercing liange I9 of the ceiling, angle iron 51 andZbar 45, or through the side by piercing only the outer wall I.

I do not claim specifically herein the various novel details ofconstruction not directed to the floor assembly shown, since they arespeciically claimed in my copendingl application Serial No. 120,322,filed Jan. 13, 1937.
